Arc'teryx designed its Women's Anertia Gore Tex Gloves to keep you're powder hungry paws warm and dry whether they're getting after it on a pow day or sniffing out the last remaining powder stashes on a warm spring afternoon. Made with a Gore Tex XCR waterproof insert, the Anertia is completely waterproof, but it is also highly breathable due to the breathable nature of the Gore Tex membrane and the Fortius 1. 0 softshell fabric that is placed along the back of the hand. The palm and fingers are reinforced by a durable leather material to resist wear and add an extra layer of protection from the elements. In terms of insulation, the Anertia is filled with two different Primaloft fibers with 133g Primaloft Silver used at the back of the hand to increase warmth and a denser Primaloft Gold material used at the palm to resist packing out over time and to deliver a more natural fit.
